Application filed March 3, 19,11. Serial No. 612,044.

I'atented Sopt. L3, 1913.

My invention relates to improvements in` sheet metal oans of theV kindhavingl slip eovers. i

The object of my lnvention is to provide a 'slip cover can suitable :foruse in shipping oysters or other articles or products, which will haveprovision for very -1 ecurely lock-` ing or holding the cover on the canand also provision for tightly closing or sealiug,` the1 can to Protectits contents against contamination, and v'which will be of a, simple andet'ticient construction, capable ot' being ('.hearply manufactnred andwhich also inny be convenientl'ut7 opened.

My invention consists in the means l einploy, and herein shown anddeseribed to practica'lly accomplish this object or result, the sameconsisting essentiallv`y in a slip cover can, the body of which isfurnished at .its month end with an external annnlar shouhler,preferalolx7 forn'ied by an internal head, and the slip cover of whichhas its tlange provided with an internal sinnnlar shoulder preferahlyforined by an internal head .on the flange of the cover and anencireling looking' wire band surroundingr the tlang'e of the slip coverand havingr a ^ontractible loop therein for ('ontraetin;r the flange ,ofthe cover about the month of the can to lock the cover on the can and tocause it to produoe a tight closnro. 'lihe tlanne of the cover has aInoteh therein for the contractible loop of the wire hand to projectthrough, and it is also preterably fnrnished with one or more fnrthernotches or slits to i enable the flange of the (-over to cxpand ande'ntract when the wire band tio'htened.

In the acconipanving` drawin;`` l'orniino' a part of this specification.Fignrc l is a central, verticiil section of a slip cover ran einhodving'nrv invention. Fin. is ;i horizontal' section on line 2 -2 of l."i`". 1.Fig'. I is a detail plan view showing' the wirl` hand before thecontractiliile loop therein is pinehed together to contract the flangeot' the cover and close it upon the can hodv. :illustratiesn modifiedconstruction in is looeencd or f which the meeting ends of the wiro bandare seem-ml to,'ether by hooks or loops instead of being' soldered orwelded together as shown in Figs. l and Figs. 5, (i, 7 and 8 are detailVertical seetionfI showing a nnniher of differentn'iodified('onstruetions o'l' the interengaging annular shoulders on the can bodymonth and cover lange respectively.

In the clra'wing, 1 represents the body of a slip cover Sheet metal canof large size'or several gallons7 capacity, such as `is comnionly'nsedfor shipnunit of oysters.

2 is the hottoni head of the ('an seeured to the body in any suitableiuanner.

The sheet nietal bodyI l of the can is preferably provided near itsupper end with the enstoniary external annnhnfibcad 23 to stillen thesame, and with a month portion -l above said head, l'n'et'erahlvyterniinatingI` in an internal annnlar roll nt the extreme upper end. Themonth portion 'l of the can body is also fnrnishod with an externalannular rover looking' shonlder (i, prel'el'ably l'ormed by an internalannnlar head '7, which prodncesan external annnlar groove in the canbody.

The slip cover 8 has a dependiug contraetihle and exfmnsible llango ll,which is provided with an internal lockin;r shoulder IO adapted loregister with and eng-age the external lookingl shonlder ll on the canbody when the cover llauggje l) is oo'ntraoted. The rover llange Sl isalso preferahlv furnished with a tlauge or roll ll which elnln'aoes theroutraotihh' wire band 1'2, which is furnished with aconlrartilh',-in1egrral loop l lo faeilitate the lightening oll [hc wirehand after the` cover has been applied to the can 'l`he meeting ends olIthe wire froui which the nire hand 'l' is l'ornied, are prefernblvioined by ;i welded. brazed or soldered ljoint l-l` as illustraled inll`i,' 1's. l and 2. They lnav. liowever. he ronnertwl h v books orloops l-ll`` l'ornied upon the ends of ilu' wiro. as illuslrated in'Fin' fl.

'l`he rover lllangg'e E) is furnished with a uoteh or (ful, awayrporlion 17 for the loop 121 of the (fontrarlihle wire band [o projectthrough` and it is also [n'eferablv provided with one or lnore 'l`urtherslits or notches '1G to faeilitate the ('onlrarting and expanding of thecover llange.

lu the niodiliration illnstratei'l in Fig 5, the external annnlarlooking shoulder 6** on the can body is shown as being formed by anexternal annular roll at the extreme upper end of the can body, and theinternal looking shoulder 1'0a on the cover flange is produced/ bythe'underhangin of the coverflange 9 when it is contracte by the Wireband l2, as Will be readily understood from the dotted lines in thisfigure.

In'thc modification illustrated in Fig. 6, the external annular lockingshoulder 6 on the can body is of the same construction as shown in Fig.1, but the internal annular looking shoulder 10b on the cover fiange isfornied byan internal annular roll 11b at the extreme lower edge of thecover fiange.

In the modification illustrated in Fig. 7, the external annular shoulder6d on the can body is produced by outwardly fiaring the month portion 4dof the can body and 'the internal annular looking shoulder 10d on thecover fiange 10 is produced by contracting the cover flange through the'agency of the Wire band 12.

In the modification shown in Fig.' 8,1the construction is similar tothat shown in Fig. 1, excepting that the cover fiange is left with astraight depending portion 17 below the internal bead or annularshoulder 1G, and the Wire band 12/ isthus not`permanently secured to thecover flange, as in the c'onstructions illustrated in the other figuresg of the drawing o In operation, after the can has been filled, the slipcover is applied to the can body, and then With a pair of pincers orother suitable implement, the integral, contractible loop 13 in' theWire band 12 is contralctedl or pinched together from the formshoWn inFig. 3 to the formshown in -Fig. 2, V'thus contracting the slip 'coverfiange of the cover and causing the'same to form a tight closure Withthe can body, and also to be very securely locked in position thereon sothat it cannot be removed Without severing the Wire band or opening upthe contracted loop 13 so as to loosen the cover fiange'on the can body.

It Will be'A noted that the canv body and I cover both being made ofsheet metal, are

adapted to be contracted When the loop in the Wire band is pinchedtogether, and after the loop has been formed the can body and cover will'expa-nd more or less to take up any s'lack wlfich may be remaining inthe band.
